ARNINNG!: When the AC Power is on, there is a potential of having dangerous voltage at the output
terminals on the rear of the amplifier. Use caution not to touch these contacts. Turn off the AC Mains
disconnect switch prior to making any connections.
1. Turn the AC Mains power switch on the back of the amplifier to OFF.
2. Connect the loudspeaker wiring to male NL4 connectors
Refer to

jumpers between output terminals that are the same points electrically. Refer to
3. Connect the male NL4 connectors to the female NL4 connectors, on the rear of the amplifier, according to your amplifier's configuration.
The following table shows you which pins on which NL4 you can use for each mode. Where there is more than one connector for a given mode, the
PLD allows you to use one, all or some of the available connectors. For example, in ABCD Parallel mode, you can use pins 1+ and 1- of NL4 (A, B, C,
and D), (A, or B, or C, or D), or (A and B), and so on; the pins are all in parallel and electrically the same point. It is recommended that where the pins
are electrically the same, you use all available pins whether by jumpers between pins, or direct wiring to each loudspeaker
